Abstract

This paper describes a blind beamforming algorithm based on maximum SINR criterion applied to the reverse link of the W-CDMA system. The maximum SINR weight vector is derived by exploiting the separation of the frequency band of the desired signal from the frequency band of the interference and noise after a despreading operation on the received CDMA signal. Thus, the algorithm applies the concept of the frequency gating to the CDMA beamforming. We call this algorithm a code gated algorithm or CGA to distinguish the use of CDMA spreading code in separating the desired signal from the interference and noise.
